+# Unsafe Fast Fork
+## DO NOT USE THIS LIBRARY
+
+This is an experimental fork with extreme changes that **intentionally break important security mechanisms and functionality** in favor of speed for certain security research workloads.
+
+The forked library version is **completely unsuitable for any type of production use** and receives no support or maintenance of any kind.
+It is published primarily as a reference for other researchers. You have been warned.
+
+The original documentation content and other references are kept as-is to limit the repository differences to upstream. However, be aware that none of the contact information, usage guidance or security guarantees still applies since this is a deliberately broken variant of the project.
+
+Thanks and credits go to https://github.com/llamasoft/secp256k1_fast_unsafe , on which many of the optimizations are based.
